3 weeks is nothing...just ease into it the 1st week and by the end of the 2nd you should be better than you were before your break. I'm into the start of my 2nd week after a 2 month break...I was totally burned out. I thought it would be very difficult to get back into it especially because I'm no spring chicken...but by the end of the 1st week I realized I was feeling pretty good and it wouldn't take me more than another couple of weeks to shift gears and approach my stride. Just bought a home gym and it took me longer than I thought it would to find what i was looking for at a reasonable price...I refused to spend any more money on gym memberships. But yeah...3 weeks is nothing...you will be fine. What brought on the gastritis?

Thanks for the post, brougham. it was from over use of Nsaids. Advil, Motrin and namely diclofenac.
